Series | [net-next,v2] iavf: use tc_cls_can_offload_and_chain0() instead of chain check | expand |
From: Jiri Pirko <jiri@resnulli.us> Date: Wed, 26 Feb 2020 09:21:57 +0100 > From: Jiri Pirko <jiri@mellanox.com> > > Looks like the iavf code actually experienced a race condition, when a > developer took code before the check for chain 0 was put to helper. > So use tc_cls_can_offload_and_chain0() helper instead of direct check and > move the check to _cb() so this is similar to i40e code. > > Signed-off-by: Jiri Pirko <jiri@mellanox.com> > --- > v1->v2: > - rebased on top of net-next (using the correct helper name) Applied, thanks Jiri.
